At the beginning of the year we announced that we would be implementing a brand new rating system for our Cook-Offs. Unfortunately its launch was delayed as we were busy tweaking and fine tuning the parameters in our algorithms to try and improve the new rating system into its best possible version. We wanted to make sure that the rating system that we put up is as good as it gets! A lot of of you have been patiently waiting for the implementation and we apologize for this delay.
Its time for good news now. The moment has finally arrived! Our new rating system has now gone live!
It is available at the link .
The contests that have been affected by this are COOK01, COOK02, COOK04, COOK05, COOK06 and COOK07.
COOK03 has not been rated as it was a team based contest.
The rating will only apply to contestants that have made at least 1 submission during a contest.
For more details about the rating system please take a look at our earlier blog here.
If you have any feedback or opinions that you would like to share with us about this new system the feel free to write in to firstname.lastname@example.org or putting up a comment below this blog post.

IIT Kharagpur presents to you the 2011 edition of Bitwise, a state-of-the-art online algorithm-intensive programming contest.
Registration is free and open to all. Contestants need to solve a set of problems posted on the site using C or C++. The solutions are evaluated, not only on the basis of correctness, but also on their execution time and space complexities.
Bitwise 2011 is scheduled to be organized on the 13th February 2011 from 1200 Hrs, IST.
Bitwise 2010 had over 4900 teams participated from a total of 1473 organizations, universities and institutes spread over 66 countries.
Enigma, a puzzle game which was incorporated as a part of Bitwise 2007. Due to its immense popularity, Enigma is back with another set of twisted questions especially designed to tantalize your brain! Enigma presents itself as an exciting and appropriate precursor to our central challenge.
Welcome to the February Programmer of the Month edition!
This month we have a young 20 year old Rudradev Basak who is our Programmer of the Month. Rudradev has been part of CodeChef since August and surprisingly, just at the age of 20 he is already considered a great programmer. In the last 5 months, he has been in the winning 4 times already, we hope this is just the start and we have a lot to see from this great mind. On behalf of the CodeChef team, we wish him good luck for the future. Now let’s see what Rudradev has to tell us about himself.
Name: Rudradev Basak
Institute: IIT Delhi
User id: rudradevbasak
Brief introduction about yourself:
I am a 3rd year student doing my B.Tech. in CSE@IITD. I have always liked to solve puzzles, both mathematical and algorithmic.
How/When did you start programming?
I learnt BASIC in middle school, and a bit of Java and C++ in standards 10 and 12 respectively. I liked to code even then, and of course I did learn a lot in my first couple of year at IITD, but I was introduced to competitive programming only in around April 2010. Also I owe it to my teammates (Nikhil and Pradeep) for getting me interested in ACM ICPC in around August last year, and I have been programming a lot since then.
What do you do when you’re not programming?
Between IITD curriculum and programming, there is not much time for much else. However when I do get time, you would find me playing games, watching movies with my friends, reading fiction or playing with a Rubik’s Cube.
What do you like most about CodeChef?
The fact that the long contests really give you time to learn and try out new things. Also it has been a great platform to boost programming awareness among Indians.
How many hours a day do you program?
Depends. Can vary from zero to ten depending on my mood and how much other work I have.
If you could eat dinner with any famous person (past or present), who would it be and what dish would you have?
Am not sure about the person, but I would probably have a couple of Chicken Rolls
What is the secret to being a good programmer?
A passion for programming, a bit of hard work (but it is not really ‘hard work’ if you really have the passion), and also some inherent math and logical ability.
And sure for success in online contests you need a lot of practice.
What are your plans for the future?
I would like to complete my undergraduate studies, and in the meanwhile, try to perform well at this (and also hopefully the next) ICPC World Finals. After that I may go for higher studies in CS, but I am not very sure.
